Material Material descriptio Advantages/Disadvantages Recurring use

It is made of acrylonitrile and butadiene

copolymerization, the acrylonitrile content is

18%-50%, the higher the acrylonitrile content,

the better the resistance to petrochemical oil

hydrocarbon fuel oil, but the low temperature

performance becomes worse, and the general

use temperature range is -40-100 °C. Nitrile

rubber is one of the most commonly used

rubbers for oil seals and O-rings.

Hydrogenated nitrile rubber is a part of the

double chain in nitrile rubber that is removed

after hydrogenation, and its temperature

resistance and weather resistance are much

higher than that of general nitrile rubber, and the

oil resistance is similar to that of general nitrile

rubber. The general operating temperature range

is -40-150°C.

There are various types of rubber with fluorine in

the molecule according to the fluorine content

(i.e., monomer structure). At present,

hexafluoride fluoroelastomer is widely used. The

high temperature resistance is better than that

of silicone, and it has excellent chemical

resistance, resistance to most oils and solvents

(except ketones and esters), weather resistance

and ozone resistance; The cold resistance is

poor, and the general operating temperature

range is -20-250°C. Specially formulated to

withstand low temperatures up to -40°C.

The main chain formed by the copolymerization

of ethylene and propylene is not double-stranded, so it has excellent heat resistance, aging

resistance, ozone resistance, and stability, but it

cannot be sulfurized. In order to solve this

problem, a small amount of the third component

with double chain is introduced into the EP

backbone and sulfur can be added to form

EPDM, and the general use temperature range is

-50-150°C. Excellent resistance to polar solvents

such as alcohols, ketones, glycols and phosphate

hydraulic fluids.

The silica gel backbone is made of silicon

(-Si-O-Si) combined. It has excellent resistance

to heat, cold, ozone and atmospheric aging. It

has very good electrical insulation properties.

The tensile strength is worse than that of general

rubber and it is not oil resistant. The general use

temperature range is -40-200°C, and the high

temperature of special formula can reach 300°C.

Advantages: The tensile strength can reach 1500PSI

after modulating the formula; Good elasticity and

good compression skewness; Good resistance to

neutral solvents; Excellent heat resistance; Excellent

cold resistance; Excellent resistance to ozone and

oxide attack; Excellent electrical insulating properties;

Good heat insulation and heat dissipation

Disadvantages: Not recommended for use in most

concentrated solvents, oils, concentrated acids and

diluted sodium hydroxide

Advantages: It has better abrasion resistance than

nitrile rubber. It has excellent resistance to corrosion,

tensile and compression. Good resistance to ozone,

sunlight and other atmospheric conditions. Generally

suitable for washing or dishwashing detergents.

Disadvantages: Not recommended for use in alcohol,

ester or aromatic solutions

Advantages: Heat resistance up to 250°C; It is

resistant to most oils and solvents, especially all acids,

aliphatic hydrocarbons, aromatic hydrocarbons and

animal and vegetable oils

molecular weight esters and nitrate-containing

mixtures

Advantages: good weather resistance and ozone

resistance, excellent water and chemical resistance,

can use alcohols and ketones, high temperature vapor

resistance, good impermeability to gas

Disadvantages: Not recommended for food use or

exposure to aromatic hydrocarbons

Seals for automobiles, locomotives,

diesel engines and fuel systems and

chemical plants

vapor environments; sanitary

equipment seals; rubber parts in the

braking (braking) system; Seals in

radiators (car tanks)

Seals or rubber parts used in the

household appliance industry, such as

rubber parts in electric kettles, electric

irons, and microwave ovens; Seals or

rubber parts in the electronics industry,

such as mobile phone buttons, new

energy vehicle connector seals, and

seals in cable joints; Seals on various

items that come into contact with the

human body, such as kettles, water

dispensers, etc

In the air conditioning and refrigeration

industry, it is widely used in the seals of

the environmentally friendly refrigerant

R134a system and the seals of the

automobile engine system.

Advantages: Good resistance to oil, water, solvents

and hydraulic fluids. It has good compression skew,

anti-wear and elongation.

Disadvantages: Not suitable for use in polar solvents

such as ketones, ozone, nitrohydrocarbons, MEK and

chloroform.

quite good, and the high hardness, high elasticity and wear

resistance are difficult to compare with other rubbers; It

also has good aging resistance, ozone resistance, and oil

resistance. The general operating temperature range is

-45-90°C.

The elastomer polymerized by Alkyl EstEr AcrylatE has

good petrochemical oil resistance, high temperature

O形圈设计建议

O RING DESIGN SUGGESTIONS

安装建议

手工安装

基本要求

使用无锐边的工具

保证O形圈不扭曲，使用辅助工具保证正确定位

尽量使用安装辅助工具

不得过量拉伸O形圈

对于用密封条粘接成的O形圈，不得在连接处拉伸

Use tools that don't have sharp edges

Make sure the o-rings don't twist and use auxiliary tools to ensure proper

positioning

Use installation aids whenever possible

Do not overstretch the o-ring

O-rings bonded with sealing strips must not be stretched at the joints

When the O-circle is stretched, it is necessary to use a mounting mandrel when

passing threads, splines, keyways, etc. The mandrel can be made of softer metal

or plastic and must not have gross margins and sharp edges.

Automated installation of o-rings requires adequate preparation. The surface of

the o-ring is usually treated in several ways to reduce the friction of the

installation and prevent sticking. Easy to separate.

Extensive experience is required in the handling and installation of parts that are

dimensionally unstable. For reliable, automated assembly, special handling and

installation of the 0-ring is required.

The initial deformation (extrusion amount) of the o-ring in the groove is

necessary for its sealing effect

1. Obtain the initial seal contact stress

2. Compensate for product tolerances (connect the two in a gap fit)

3. Ensure a certain amount of friction

4. Compensate for permanent compression set (loss)

5. Compensate for wear and tear

For different applications, the ratio of the initial deformation to the cross-section

diameter (d2) is listed below

Dynamic seal application: 6%-20%

Static seal application: 15%-30%

安装过螺纹、花键等

自动化安装

压缩率

当O形圆拉伸后，要通过螺纹、花键、键槽等时，必须使用安

装心轴。该心轴可以用较软的金属或塑料制成，并不得有毛利

和锐边。

自动化安装O形圈要求有充分的准备。通常对O形圈的表面用

几种方法来处理，以减小安装磨擦力小、防止粘连。容易分

离。

对于那些尺寸不稳定的零件的处理与安装，需要丰富的经验。

要获得可靠的自动化装配，需要对0形圈进行特别的操作和安

装。

O形圈在沟槽中的初始变形(挤压量)对其密封作用是必要的

1.获得初始密封接触应力

2.补偿产品公差(在间隙配合中连接二者)

3.保证一定的摩擦力

4.补偿永久压缩变形（损失）

5.补偿磨损

对于不同的应用，下面列出了其初始变形量与截面直径(d2)的

比例

动密封应用：6%-20%

静密封应用：15%-30%

INSTALLATION RECOMMENDATIONS

Are the lead-in corners machined according to the drawing?

Does the inner diameter remove burrs? Are sharp edges rounded?

Have process residues, such as debris, dirt, foreign particles, etc., been

removed?

Is the thread tip covered?

Are seals and parts greased or oiled? (To ensure compatibility with elastomers,

it is recommended to lubricate with a sealed fluid.)

Before insvtalling an o-ring, check the following:

引入角是否按图纸加工?

内径是否去除毛刺？锐边是否倒圆？

加工残余，如碎屑、脏物、外来颗粒等，是否已去除？

螺纹尖端是否已遮盖？

密封件和零件是否已涂润滑脂或润滑油？

（要保证与弹性体的介质相容性，推荐用所密封的流体来

润滑）

不得使用含固体添加剂的润滑脂如：二硫化钼、硫化锌。

在安装O形圈之前，检查以下各项：

Greases containing solid additives such as molybdenum

disulfide and zinc sulfide should not be used.

COMPRESSIBILITY

Automated Installation

Installation of threads, splines, etc

Manual installation

Basic Requirements

O型密封圈系列

O-ring series

技术参数

工作压力

The correct groove design can eliminate possible damage and seal failure right

from the start. Since the o-ring is squeezed during installation, it is necessary to

design the parts that come into contact during the introduction of the o-ring

with a defined chamfer and rounding.

沟槽设计

正确的沟槽设计可以从一开始就消除可能的损伤和密封失

效。由于O形圈安装时受挤压，所以设计O形圈导入过程

中接触的零件时，必须要有规定倒角和倒圆。

O形圈可以广泛应用在各种环境。环境的温度、压力、速

度和介质决定了密封材料的选择。为了正确地评估O形圈

是否对某种具体应用适用，我们必须对所有的工作参数及

其相互影响予以考虑

O-rings can be used in a wide range of environments. The temperature, pressure,

speed and medium of the environment determine the choice of sealing material.

In order to properly assess whether an o-ring is suitable for a particular

application, it is important to consider all operating parameters and how they

affect each other

内径大于50mm的O形圈在5Mpa以下工作时，不需要挡

圈;内径小于50mm的0形圈在10Mpa以下工作时，不需要

挡圈;(与材料硬度、截面尺寸、间隙有关系)40Mpa以下，

必须使用挡圈;50Mpa以内，使用特殊的挡圈。注意最大

许可间隙。

压力小于5Mpa的往复运动，不需要使用档圈

大于5Mpa,必须使用档圈。

动密封

往复运动速度最大0.5m/s

旋转运动速度最大0.5m/s

The maximum reciprocating speed is 0.5m/s

The maximum speed of rotational motion is 0.5m/s

-60°C to 325°C (depending on material type and media compatibility) Extreme

temperatures and continuous operating temperatures are taken into account

when evaluating them. For moving

Special attention should be paid to sealing, the temperature increase due to

frictional heat generation.

-60℃至+325℃(与材料种类和介质相容性有关)在评估

时，极端温度和连续工作温度都要予以考虑。对于动

密封，由于摩擦生热造成的温度升高，要特别注意。

由于有着许多具有不同特性的密封材料可供选择，德克的

密封件可满足几乎所有液体、气体和各种化学介质的使用

要求。

With a wide range of sealing materials with different properties to choose from,

Dirk's seals meet the requirements of almost all liquids, gases and various

chemical media.

静密封 Static sealing

O-rings with an inner diameter greater than 50mm do not need retaining rings

when working below 5Mpa; 0-ring with inner diameter less than 50mm does not

need a retaining ring when working below 10Mpa; (related to material hardness,

cross-sectional size, clearance) below 40Mpa, must use retaining ring; Within

50Mpa, a special retaining ring is used. Pay attention to the maximum permissible clearance.

Dynamic sealing

The pressure is less than 5Mpa reciprocating motion, and there is no need to use

a gear ring

If it is greater than 5Mpa, a gear ring must be used.

端面密封沟槽设计建议(轴向) Recommendations for Face Seal Groove Design (Axial)

在压力作用下，弹性体将贴紧不规则的密封表面。对气体或液体密封的紧配合静密封，被密封表面应满足一些基本

的要求。密封表面上不得开槽、划痕、凹坑，同心或螺旋状的加工痕迹。对于动密封，配合面的粗糙度要求更高。按照PIN4768/1

和ISO1302标准中对表面粗糙度的定义，我司对沟槽各个表面的粗糙度要求推荐如下表

Under pressure, the elastomer will adhere to the irregular sealing surface. For the tight fit static sealing of gas or liquid seals, the sealed surface should meet some basics

requirements. There shall be no grooves, scratches, pits, concentric or spiral processing marks on the sealing surface. For dynamic seals, the roughness of the mating

surface is required to be higher. According to the definition of surface roughness in PIN4768/1 and ISO1302 standards, our company recommends the roughness

O形圈在轴向发生变形。在压力作用下，O形圈会产生径向运动，所以要注意压力的方向

若压力来自内侧，则O形圈的外径应该与沟槽的外径接触(其周长压缩1%到3%)

若压力来自外侧，则O形圈的内径应该与沟槽的内径接触，最大允许拉伸3%

O-rings are axially deformed. Under pressure, the o-ring will produce a radial motion, so pay attention to the direction of the pressure

If the pressure is coming from the inside, the outer diameter of the o-ring should be in contact with the outer diameter of the groove (its circumference compressed by

1% to 3%)

If the pressure comes from the outside, the inner diameter of the o-ring should be in contact with the inner diameter of the groove, allowing a maximum stretch of 3%
